RADIATOR Filed Nov. 19, 1928 VIII/{IIIIIII 'IIIIIIIIIIIA Patented Aug. 23, 1932 UNITED STATES PATENT OFFICE OWEN L. SEWARD, OF NEWINGTON JUNCTION, CONNECTICUT, ASSIGNOR TO THE BUSH MANUFACTURING COMPANY, OF HARTFORD, CONNECTICUT, A CORPORATION OF CONNECTICUT RADIATOR Application filed November 19, 1928. Serial No. 320,248.

My invention relates more especially to that class of devices employed for heating or cooling fluids, more particularly liquids,-and an object of my invention, among others, is 5 the provision of a device of this class that shall be simple in construction and particularly efficient in operation.

One form of device embodying my invention and in the construction and use of which w the objects herein set out, as well as others,

may be attained, is illustrated in the accompanying drawing, in which Figure 1 is a view in section through a fragment of a radiator embodying my invention.

Figure 2 is a plan view of a radiator element embodying my invention.

Figure 3 is an isometric view of the same.

Figure 4 is a View, scale enlarged, in section through the device on a plane denoted by the dotted line 4-4 of Figure 3.

While a device embodying my invention may be constructed in various sizes and embodying one or more elements constituting my improved structure, in order to simplify the disclosure contained herein I have illustrated a structure or element embodying a single tube. It will be understood, however, that any suitable number of tubes may be employed in a completed structure, and thatthe radiating plates may be larger or smaller than those shown herein and may be provided with means for receiving one or any number of tubes.

In the accompanying drawing the numeral 5 denotes a tube constituting a part of my improved radiator and through which fluid or liquid may be circulated, as is common to structures of this class, for the purpose of changing its temperature. A number of radiating plates 6 are provided with openings 7 through which the tube 5 extends, the plates being secured to the tube as by an expanding process in a manner common to devices of this class and, therefore, readily understood by those skilled in the art.

In carrying my invention into effect I provide each of the plates 6 with spacers 8 pref erably formed integrally with a plate and bent substantially at right angles thereto. In the particular structure herein shown these spacers comprise lugs that are bent A outwardly from openings 9, the openings being created for the purpose of providing the lugs. These spacers or lugs and the openings are so formed that when the lugs are positioned to act as spacers they will abut against the flat surface of an adjoining plate and will not enter the openings 9. In the structure shown herein the openings 9, and consequently the spacers, taper from a wider dimension at the free end of the spacer to a narrower dimension at the root thereof so that when the spacer is in position the wide end will be located opposite the narrow end of the opening 9 and, therefore, cannot pass 1nto said opening. It will be understood that this result may be obtained in various ways by bending a spacer or lug of various forms from Within an opening created to provide said lug, the structure herein embodying one only of said different forms.

In accordance with the provisions of the patent statutes I have described the principles of operation of my invention, together with the device which I now consider to represent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim 1 A radiator element including a circulatlng tube, a plurality of radiating plates through which said tube extends, and spacers constituting integral parts of each plate and bent at an angle thereto from the body thereof leaving an openingtherein to form said spacer, the outer end of said spacer being wider than that part of the opening in an adjacent plate inproximity to which it lies, said spacers being arranged around the tube with the inner larger ends of the openings disposed adjacent the tube.

2. A radiator element including a circulating tube, a plurality of radiating plates of rectangular form in plan view through which said tube extends, spacers for the plates struck out from the four corners of each plate, each spacer being of trapezoidal form its wider end disposed a defining a similarly sha ed opening having d acent the tube with the wider end of the spacer engaged with the adjacent plate at the narrower end of the opening to extend across the same forthe spacing of the plates.

3. A heat exchange device comprising-a tube, and a series 0 fin plates surrounding said tube and projecting outwardly therefrom in spaced relation to each other, each ofsaid fin lates having spaced lugs punched out from t e body of the plate and adapted to en age the next adjacent plate for holding t e lates in spaced relation, said In s bemg o greater width at their outer ends than at their inner ends to prevent the lugs of one plate from entering the lug-apertures of the next plate.
